When buying metal gutters, choose the thickest metal available and look for primary or virgin materials.
当购置金属水槽，最厚地金属可供选择，并等待为小学或原生资料。
But the most effective policy would be to incorporate the costs of the pollution caused by gathering and processing virgin materials into their prices.
不过，把收集与加工原始生产材料所产生的污染成本计算到总成本中，才是最有效的措施。
At the moment, it is often cheaper to process virgin materials, despite the extra energy required, because collecting and sorting recyclables is so labour-intensive.
目前，尽管原材料加工需要额外的能源，但往往很便宜，因为回收时收集和分类需要更多劳动力。
But perhaps the most valuable benefit of recycling is the saving in energy and the reduction in greenhouse gases and pollution that result when scrap materials are substituted for virgin feedstock.
然而，垃圾回收最大好处可能是能量的节省与温室气体和污染的降低，当废料当作原料使用时就会产生污染。
PE6002 is made of the joint-ventured raw materials with matt surface and good dispersion. The compound can be diluted with 30% virgin resin.
